My TH200-4R rebild is approaching 100,000 miles and it just now starting to shift a little sloppy. The Dexron fluid is clear red and smells O.K. Will Type F or B&M TrickShift firm it up? Will putting Type F in make things wear out faster? I want to keep the Olds alive a little while longer. I keep it around to get parts, tow trailers, and other pack mule jobs. There's nothing like driving a big beater on a dirt road, either!

 

type f fluid will make your trans shift firmer. i've never used all type f, but have mixed it about 3 to 1 type f to dextron.

yeah i was wondering about this one too. i heard it will make you shift harder, now what i was wondering if i would have any improvement if used in a manual tranny like a t-5 that uses dexron, would there be any improvement?

don't think it would matter in a manual trans. type f is made for ford, as we all know ,because ford uses les clutches in their automatics so they need something that will not slip as much as dextron would.

No, if anything it would be bad. Oil for your stick shift needs it's oil to be as clean as it can be, code F contains more additives, which is the opposite of what you want. If anything buy Redline brand oil for it. For a review of redline oil checkout this link http://www.c5-corvette.com/redline.htm

Changing the fluid and filter is the conventional 1st step to fixing any auto tranny problem. I wouldn't say that the change to Type F would be the right answer for you, though.

 

actually my T-5 manual transmission calls for dexron 2 or equivalent, it doesnt say to use gear oil.

The T-5 trannys that use ATF are called "World Class" transmissions. Rougher, tougher, more heavy duty!! I just bought one.

 

What would the effects of Type F be on a 700R4 or a 200R4? How about long term use? Is it good for the transmission or bad?

The Type F is supposed to give firmer shifts. The long-term effects are no different than using Dextron.

If you want a REAL ATF, use AMSOIL synthetic. It is rated as both Dextron and Type F, and gives lubrication and temperature benefits that you will never see with petroleum-based ATF, whether Dextron or Type F.

Using type f won't hurt your tranny at all. There is a federal mandate that all trans fluids must be compatible. The major difference between type f and dextron is that F has a higher coefficient of friction than dextron which initiates clutch lockup quicker. I plan to use f in the 200 that will go in my car. To clean up sloppy shifts you can put in a shift kit but it is on it's way out.

If that is true, that is the first time I've heard it. Since Chyrsler just came out with their own type, I seriously doubt it is true.

 

is it true that the world class t-5`s use dexron II and that the earlier t-5s use gear oil? cause my 87 calls for dexron, and i thought that they didnt start using the EC t-5 until 88 ,

The type "F" was designed for use with Asbestos clutches, the type found in Ford till 1977. From then on paper type clutches are used in everything. According to Borg Warner, Raybestoes, & Hydramatic, the type "F" fluid has apx. 12-17% less holding power on dynamic clutches and bands when compared to approved Dexron 3. Ford type "F" has more static holding power,(neutral to drive) but this is not a problem with any 700R4 or 2004R transmission. When GM transmissions come in that have ran type "F" fluid, we have seen faster wear on parts. I would stay away from type "F", B&M Trick Shift or equvilant. If you like synthetics use Amsoil (best) or Red Line (2nd best).
Hope This Helps!!!

 

Fastcamaro, yes it is true that earlier t-5's used gear oil and later ones used dextron II or better. According to my chiltons 1982-1984 used gear lube and 1985 and up used dextron II.

 

FASTCAMARO... I have an 87 w/ a t-5 and everything I have says it uses a special gm part number (1234931) or something like that...

zroc...

 

That is totally wrong! Every literature I have seen on ('84) Camaro's and fluid specs call specifically for AC-Delco Dexron II/Mercon. Even my 1984 GM manual states that. All T5 use Dexron II/Mercon.
